To all whom t may concern.'

Be it known that I, RAFFORD PITT, a citilzen of the United States, and aresident of This invention relates to improvements in door hangers.

By the use' of my invention I am enabled to produce a door hangerpreferably of the ball-bearing type which will not only be very light inweight, noiseless and inexpensive to manufacture, but will be free fromdust and dirt, consequently permitting the movement of a door to whichit is attached with great facility, and said hanger will also have greatrigidity and durability.

In the preferred embodiment of my invention which comprises a stationarymember and a member movable relatively thereto, the stationarymember isrolled from sheet metal to provide a t-rack portion preferably withraceways for balls or other similar antifriction devices, and has asecuring portion in the form of a Harige integral and preferablyco-extensive with said track portion, said integral` securing flangeforming a shield against the admission of dust to the raceways in thetrack portion of said stationary member and providing a flat securing'surface for said stationary member, thus enabling the same to besecured at various points over the doorway, and adding rigidt sity tothe structure without undue weight.

vThe movable `member is also preferablyl rolled from sheetY metal bentto provide a track portion with raceways registering with the racewaysin the stationary member to form channels to receive balls or otheranti-friction devices and a securing portion `iin the form of a flangeintegral andl preferably co-extensive with said track portion so as toprovide a ready device for securing the movable member rigidly andsecurely to the door and keeping out dust and dirt from the operatingparts thereof, balls be tween the raceways in the movable and staftionary members and ball-containers preferablyfcomprising two abuttingand connected lstrips of sheet metal ribbed longitudinally to a'ordrigidity and provided with 'ball-containing pockets formed by cut-4 tingspaced and registering apertures in each of the abutting strips andblistering7 or bending the edges of the lower strip downwardly andblistering or bending the edges of the apertures of the upper stripupwardly, whereby a pocket is formed for the balls.

Figs. 8 and 9 are sections at right angles to each other of a ballpocket or ball seat in said container; and

Fig. 10-is a side elevation of a construction embodying a modifiedarrangement of the ball containers.

Referring now to Figs. 1 to 3 and 5 to 9 inclusive, l indicates the wallsurrounding a doorway, 2 the stationary member of a hanger embodying myinvention which is preferably of the cross-sectional form shown in Figs.3 and 6 and comprises a track portion 2a and a combined securing portionand dust shield 2b provided along its length with suitable screwapertures to permit fastening thereof by screws 3 to the doorway. Thesaid stationary member, as shown, is preferably co-eXtensive with thedoorway and is preferably rolled up from a strip of sheet metal toprovide intermediate the longitudi-V nal edges of said strip, tracks orraceways 2c, 2d and 2e respectively, terminating at one longitudinaledge in the flange 2b which eX- tends at an angle to said track portion,the other longitudinal edge being so disposed with. relation to saidflanged portion that when the said stationary member is secured.,

I to the doorway an entrance or operating slot 2' will be provided topermit the reciprocation therein of the door connecting ortions of themovable member hereina ter described.

The movable member 4 of the hanger also preferably comprises a trackportion 4a and flange portion 4b which 1s preferably provided Withsuitable screw a ertures and 1s connected along the upper e ge of thedoor n by screws. Said movable Vmember is, as

shown, preferably co-extensive with the.

transverse edge of the door and is also preferably rolled up from astrip of sheet metal to provide intermediate the longitudinal edges ofsuch strip, tracks or raceways 4, 4d and 4*3 respectively which reglsterwith the tracks or raceways 2c, 2d and 2e of the st ationary memberandone edge of saldl strip terminates in the said securing flange 4b whichis of such conformation and is so disposed with relation to thestationary member as to extend through the slot 2f and permit attachmentof said track portion to'the door.

In Fig. 4 said securingflange is angular in conformation, Figs. 3, 5 and6 lllustrating the same as extendlng upwardly from the track-portion andthence outwardly through the slot 2f and downwardly to the door where itis'secured in any sultable manner. n

In Figs. 3 and 5 said flange 1s shown as secured at one side of the dooradJacent to the top edge thereof, and in Fig. 6 as abutting against andsecured to the top transverse edge of the door.

In Fig. 4 I have illustrated a hanger embodying a modified form of mylnventlon in which the stationary member is rolledup from a sheet ofmetal 10 to provide a track portion 10a having longitudinal raceways10c--10d and a securing flange 10b'at one longitudinaledge thereof, theopposite longitudinal edge being so disposed in rela-' tion to saidflange 10b as to provide an operating slot 10f. The movable member lisalso preferably rolled up from a single strlp of sheet metal to providea track portion 14 having ball raceways 14a-14b registering with theraceways 1()c and 101 of the stationary member to form ball channelstherebetween, one longitudinal edge of said strip being bent to providea flange 14c to permit the securing of the same in any sultable mannerto the door.

In all the figures of the drawings I have illustrated balls 7 interposedin the ball channels formed between the longitudinal raceways of thestationary and movable l members respectively and these balls arepreferably seated in ball-containing pockets formed in ball containers 8comprising two abutting and connected strips of sheet metal 81-8",ribbed longitudinally to afford Maaate rigidity and pierced with spacedapertures, the edges of which apertures are blistered or bent upwardland downwardly as illustrated in Figs. 8 and 9 to provide such pockets.

Separate hall containers are preferably provided for each set of balls.rIhus in the construction shown in Figs. 3, 5 and 6, separate ballcontainers will be provided for the upper hold-down balls which arepreferably disposed above the container for the lower or carryin ballsand in the relationship shown in ig. 1, namely, the ball-'container forthe carrying balls extends substantially three-quarters of the length ofthe stationary member and the containers for the hold-down balls extendsubstantially onehalf of the length of the door which it is 'desired tohang, and is disposed centrally above the carrying-ball container.

Stops are also preferably provided at suitable points to prevent acreeping of the balls and as shown in said Figs. 1, 3, 5 and 6 stops 20are attached by screws 20L at each end of the'stationary member and suchstops close or seal up the ends of the said stationary member, thusadding to the dustproof characteristics of the device. Stops 40 are alsopreferably provided at opposite ends of the door to limit the movementof the hold-down ball-container with relation to the carrying-ballcontainer, so that during the continuance of such movement saidcontainer will always be' in substantially the same disposition to thecarrying-ball container, though both containers will change theirpositions relatively to the door and stationary member, and the saidstops 40 are preferably of the configuration illustrated in Fig. 6 so asto limit the movement of the hold-down ball-containers only whilepermitting free movement of the carryingball containers.

In- Fig. 10, I have shown a construction in which the container for theupper or hold-down balls may be equal in length to the container for thecarrying balls. yIn this construction, the stops 20 at the ends of thedoor orl movable member may be omitted. Such an arrangement ofcontainers is suitable for the construction shown in cross-section inFig. 4, though it may be employed in the construction shown incross-sectioniin Figs. 3, 5 and 6. With said last mentioned arrangementof containers, however, the upper ball container.

istl

Laagste;

permanently magnetic, and 4counsefpiently the balls lof the upper orhold-down ballcontainers will be retained against the track or tracksbelow which such balls abut.

In other respects, the construction shown in Fig. is similar tothat'illustrated in Fig. 1.

If desired, eitherv of the constructions may be so magnetized and whilesuch magnetizing of the track member willfhold the balls against therespective tracks so` that` it will be unnecessary to connect the condtainers by a Web or the like, it will have no eifect upon the movementof such balls or containers in relation to the tracks.

Another feature of my invention is the provision in a hanger of the'type'speciied of a wiping element adapted to close .the space betweenthe stationary and movable members and therefore keep out any dust fromthe movable parts, and also keep out cold air .and draftsfwhich areordinarily admitted through the spaces betweenthe parts of ball bearingAdoor hangers.l
